两种或两种以上化学元素的化学反应性非理想等离子体的相平衡与具有固定化学计量的“普通”物质的情况根本不同。高温化学反应性混合物中的相变，包括含铀化合物中的相变，对于许多现代核能装置[1]和未来核能装置[2，3]都是典型的。这种两相系统的基本特征是它们的非一致性，即它们能够改变共存相的化学计量而不违反本体化学计量。非一致性显著改变了此类系统中所有相变的性质，即：
Phase equilibrium in chemically reactive non-ideal plas mas of two or more chemical elements differs fundamentally from the case of “ordinary” substances with fixed stoichiometry. Phase transitions in high-temperature chemically reactive mixtures, including those in uranium-bearing compounds are typical for many nuclear energy devices both contemporary [1] and perspective [2, 3]. The basic feature of such two-phase systems is their non-congruency i.e. their ability to vary stoichiometries of coexisting phases without violation of the bulk stoichiometry. The non-congruency changes significantly the properties of all phase transitions in such systems, namely: (A) - The significant impact of the
